BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water jet cleaner, and more particularly, to an ultrasonic water jet cleaner in which an ultrasonic device is provided at a part of a jet port to improve a low flow rate and low pressure cleaning condition. In general, the water jet cleaner is sprayed with a high pressure water through the nozzle to remove foreign substances on the floor and the contaminated water is cleaned through the suction port provided in the vicinity of the nozzle. As the configuration of the water jet cleaner, the configuration of the water jet cleaner applied by the applicant is shown in FIGS. 1 and 2. According to FIGS. 1 and 2, the water jet cleaner 1 is roughly configured by including an upper body 2, a lower body 3, a recovery pipe 4, and a supply pipe 5. The upper body 2 is provided with a motor pump 6, a supply line (7) (7a), a suction motor (8) and a fan (9), the controller 10, and a warning light / warning device (11) , Is provided. In addition, the lower main body 3 is provided with a feed container 13 and a recovery container 14 around the separation plate 12 on the left and right sides. The recovery pipe 4 and the supply pipe 5 is connected through the upper body 2, the recovery pipe 4 is connected to the recovery container 14, the supply pipe 5 is connected to the supply line (7). In addition, the end of the recovery pipe 4 is provided with a recovery pipe head (15) for the suction of contaminants, the handle and the control switch 16 is installed in the middle. An injection nozzle 17 is connected to the end of the supply pipe 5. Reference numeral 18 denotes a moisture filter, and 19 and 20 indicate a water level sensor. The water jet cleaner 1 thus configured is provided for the handle and the control switch 16. When the motor pump 6 and the suction motor 8 are operated, the water of the feed container 13 is sucked by the motor pump 6 into the supply line 7a into which the water supply line 13 is inserted, thereby supplying the supply line 7 and the supply pipe 5. ) Is injected into the floor through the injection nozzle 17 provided at the end of the supply pipe 5. Therefore, the contaminated floor is cleaned by the strong injection force, and the contaminated water of the floor soiled by the cleaning is The suction pipe head 15 supporting the injection nozzle 17 is sucked due to the operation of the suction motor 8 installed in the upper body 2 and the fan 9 connected to the suction motor 8. This is because the suction force is generated, and the contaminated water sucked into the recovery pipe head 15 follows the recovery pipe 5. It is transported and collected in the recovery bin 14. At this time, the moisture or light contaminants of the contaminated water collected in the recovery bin 14 are blocked by the moisture prevention filter 18 or the like, so that the suction motor 8 is protected. On the other hand, the level of water in the supply tank 13 is detected by the sensor 19 to recognize the re-supply time of the water by operating the warning light / warning device (11) having the upper end of the upper body 2 is installed, The contaminated water level in the recovery container 14 is detected by the sensor 20 to recognize when to remove the contaminated water collected by operating the warning light / warning device 11. However, the water jet cleaner of this configuration There are a number of problems, such as: cleaning is caused by water spraying force, so it is necessary to generate high pressure jetting force, which is a constant pressure despite the different pollution state of the floor. This is because when the water is sprayed, the polluted state remains unremovable even by the spraying force, and thus, in order to remove the maximum polluted state, high pressure spraying force must be generated. The airtightness of the main body becomes difficult, followed by another problem in which severe noise is generated in the motor pump to generate a high pressure. In addition, since the cleaning is performed only by water spraying, a lot of water is required, and the water supply and recovery containers for filling such a large amount of water become large, and accordingly, the problem that the volume of the water jet cleaning itself becomes large also follows. do. Therefore, the convenience of the user is impaired. In addition, even when recovering a large amount of spilled water to improve the performance of the suction motor is also a problem that must increase the suction power. An object of the present invention was devised to solve the above problems of the conventional water jet cleaner, by using ultrasonic waves to improve the cleaning state even with low flow rate, low pressure water, noise reduction and volume of the main body of the cleaner The present invention provides an ultrasonic water jet cleaner that can be reduced.

In order to achieve the object of the present invention, the ultrasonic water jet cleaner according to the present invention is connected to the upper body, and the water is installed by installing the ultrasonic device to generate ultrasonic waves to the bottom of the bottom of the recovery pipe head of the contaminated water collection pipe provided outside. It is characterized in that the ultrasonic floor is irradiated to the sprayed floor.

This feature of the present invention, that is, it is possible to easily peel off and remove foreign matters that are not removed only by water injection by ultrasonic generation, thereby improving the cleaning state even with a small flow rate and low pressure water, and reduce the volume of the cleaning body. At the same time, high suction force is not required, and airtightness is easily effected.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the present invention will be described in detail, the overall sign of the water jet cleaner will be used the same reference numerals in the water jet cleaner of Figs. 3 is an overall configuration diagram of the ultrasonic water jet cleaner according to the present invention, and FIG. 2 is a cross-sectional view of the main body for explaining the main body configuration of the ultrasonic water jet cleaner.

3 and 2, the ultrasonic water jet cleaner 30 according to the present invention includes an upper body 2, a lower body 3, a recovery pipe 4, a supply pipe 5, and an ultrasonic device 31. It is composed roughly including.

The upper body 2 is provided with a motor pump 6, a supply line (7) (7a), a suction motor (8) and a fan (9), the controller 10, and a warning light / warning device (11) It is provided. The lower main body 3 is provided with a feed container 13 and a recovery container 14 on the left and right sides of the separator plate 12. The recovery pipe 4 and the supply pipe 5 is connected through the upper body 2, the recovery pipe 4 is connected to the recovery container 14, the supply pipe 5 is connected to the supply line (7). In addition, at the end of the recovery pipe 4 exposed to the outside of the main body is provided with a recovery pipe head 15 for suction of contaminated water, the recovery pipe head 15 is provided with an ultrasonic device 31 according to the present invention. . The supply pipe 5 is installed along the recovery pipe 4, and an injection nozzle 17 is provided at an end thereof. A handle and an adjustment switch 16 are installed in the middle of the recovery pipe 4. Reference numeral 18 is a moisture prevention filter for protecting the suction motor 8 by blocking moisture in the recovery container 14, and 19 is a sensor for notifying the water resupply timing by detecting the water level in the supply container 13, 20 Is a sensor for detecting the water level in the recovery container 14 to inform the timing of removal of contaminated water, 32 is an ultrasonic horn for generating ultrasonic waves, and 33 is for diffuse reflection of ultrasonic waves generated in the ultrasonic horn 32. It is a metal mesh, and 34 is a control for adjusting the frequency of ultrasonic waves.

The operation and effects of the ultrasonic water jet cleaner thus constructed will be described. As shown in FIGS. 2 to 3, when the motor pump 6 and the suction motor 8 are operated by the knob and control switch 16, the water in the feed container 13 is driven by the motor pump 6. This is sucked into the supply line (7a) inserted into it is fed to the supply line (7) and the supply pipe (5), it is sprayed on the floor through the injection nozzle 17 provided at the end of the supply pipe (5).

At the same time, the ultrasonic device 31 is operated so that the ultrasonic horn 32 generates ultrasonic waves and irradiates ultrasonic waves to the water sprayed on the floor. The ultrasonic horn 32 irradiates the ultrasonic waves toward the bottom of the sprayed water because the ultrasonic waves propagate to the bottom. Therefore, the irradiated ultrasonic waves cause vibrations in the sprayed water on the floor, thereby making it possible to easily remove foreign substances on the floor which are not sufficient by water injection pressure alone. At this time, by the control knob 34 installed on the knob and the control switch 16 to optimally select the ultrasonic frequency according to the state of the floor. That is, the frequency is initially maximized within the frequency range that can be initially set by adjusting the adjustment knob 34 according to the degree of cleaning when the dust adheres to the floor, and at the end, the energy is reduced and the maximum is cleaned. It can be effective. The frequency range can be selected from the range of the frequency of 15-50 KHz, for example.

In addition, by installing the metal mesh 33 around the ultrasonic horn 32 so that the ultrasonic wave generated in the ultrasonic horn 32 is diffusely reflected by the metal mesh 33, the irradiation of ultrasonic waves is performed around the injection nozzle 17. It can be extended to the bottom widely (shown in Figure 4). Thus, the ultrasonic wave is irradiated to the water sprayed on the floor by the ultrasonic apparatus 31 together with the injection pressure of the injection nozzle 17, so that the floor is efficiently cleaned, and the contaminated water of the cleaned and dirty floor is the injection nozzle 17 And suction tube head 15 supporting the ultrasonic apparatus 31. This is because the suction force is generated due to the operation of the suction motor 8 installed on the upper body 2 and the fan 9 attached to the suction motor 8. The contaminated water sucked into the recovery pipe head 15 is transported along the recovery pipe 5 and collected in the recovery container 14. At this time, the contaminated water and agglomerated contaminants transported along the recovery pipe 5 are lowered to the recovery container 14, and some fine water and light dirt are blocked by the screen or the moisture prevention filter 18, and thus the suction motor. (8) is to be protected.
